David Binder, a pollster who worked for the Obama campaign, conducted a poll for Weiner asking, "'Are voters willing to give him a second chance or not, regardless of what race or what contest?' And the answer? "There was this sense of 'Yeah, he made a mistake. Let's give him a second chance,'" Binder told The New York Times. "But there are conditions on that, and there are a couple of things we're going to want to know: What have you been doing since this incident occurred? Did you learn anything from this mistake? How did you deal with it?' They want to know that they've put it behind them."

Weiner is not the first politician to try to make a comeback after a scandal. Former South Carolina Gov. Mark Sanford resigned after news that he was having an extramarital affair came to light. He's now running for Congress. Newt Gingrich, who was sanctioned by Congress over an ethics issue and stepped down as speaker, ran for president last year.

Political and public relations consultant David Johnson and political scientist Michael Miller join The Daily Circuit to talk about what it takes to come back from a scandal and what voters are willing to forgive.
